BLOCK FOR X-RAY DENTAL FILMS Filed Feb. 3, 1930 F/ar/and Mar/1'27INVENTOR ATTORNEY Patented Feb. 28, 1933 I'LoaIAN J. MARTIN, orMEDFOLRD, w sooNsIN BLOCK FOR X-RAY DENTAL FILMS Application filedFebruary 3,1930. Serial No. 425,592.

The present invention contemplates the provision of a dental X-ray filmholder, constructed to permit the film to be quickly and convenientlyassociated therewith or removed therefrom, and when associated therewithit is held in proper position with relation to the tooth by clamping theholder between the teeth.

One of the chief characteristics of the present invention resides in theprovision of a holder of the above mentioned character, constructed, ordesigned to accommodate a modeling compound adapted to be arrangedbetween the teeth of the patient to receive the impression of the teeth,so that should a second picture be desired or necessary of the sametooth at a different angle, theimprint of the teeth in the modelingcomposition would insure the holder being placed in the exact positionwhich is formerly occupied in the patients mouth.

The nature and advantages of the invention will be better understoodwhen the following detailed description is read in connec' tion with theaccompanying drawing, the invention residing in the construction,combination and arrangement of parts as claimed.

In the drawing forming part of this application like numerals ofreference indicate similar parts in the several views, and whereinFigure 1 is a view showing how the holder is clamped between the teethof the patient, and how the relatively soft modeling composition isused.

Figure 2 is a front elevation.

Figure 3 is a top plan view.

Figure 4 is a sectional view on line 4-4 of Fi ure 2.

igure 5 is a top plan view with the modeling composition removed.

Figure 6 is a transverse sectional view through Figure 5.

The film holder forming the subject matter of the present inventioncomprises a b ase 10 which may vary in size and contour withoutdeparting from the inventive idea, and a front wall 11, the latterrising an appreciable distance above the base and spaced therefrom for aportion of its length to define a film receiving groove 12. Theholder-in its entirety may be constructed from any suitable materialwhich may also vary in size to ac-. commodate films of differentdimensions, the film being placed in the groove 12, and held fixedrelatively to the'holder by means ofsuitable screws or other fasteningelements 13 carried by the front wall 11. The base 10 is designedtoaccommodate a modeling com position of relatively soft material, uponwhich the patient is adapted to bite, and thereby leave the impressionof the teeth or tooth'being X-rayed as will be readily appreciated. Thecomposition indicated at 14' is relatively soft for this purpose, butwill readily harden when removed from between the teeth of the patient,thereby" leaving the,

impression of the teeth in the composition for a purpose to be presentlydescribed; Inaccordance with the preferred embodiments of the inventionas clearly illustrated in Figures 5 and 6, the base 10 is provided withan open-,

ing 16 to receive the composition 14, while the walls of the base aboveand below the opening 16 are slightly beveled or tapered as at 17,- topermit spreading ofjthe composition when it is bit upon between theteeth of the patient.

In practice, the film 21 is placed in the groove 12 and the fasteningelements 13 are tightened to hold the film fixed relatively to theholder. The modeling composition 14 is then associated with the base 10,and the holder placed between the teeth of the patient, the latterbiting down upon the composition 14 as illustrated in Figure 1. As abovestated the composition is relatively soft to receive the impression ofthe teeth of the patient, but will readily harden after it is removedfrom the mouth of the patient. After the picture has been taken theholder is removed, and the film 21 separated from the holder.

However, it is sometimes desirable to take a second picture of the sametooth, or a picture at a different angle from that taken by the firstpicture, whereupon a second film is associated with the same holder, andthe latter again placed between the teeth of the patient. Inasmuch asthe modeling composition is now provided with the impression of thepatients teeth, it is manifest that the modeling composition wouldinsure the holder being placed in the exact position between 5 the teeththat it formerly occupied in the patients mouth. Consequently the secondfilm is again held in exactly'the same relative position with relationto the tooth as it initially occupied for the first picture.

" It is, of course, to be understood that the molding compound is usedonly when itis desired to take a second picture, namely one. to take astereoscopic view, which gives the third dimension. However, when asecond picture is not necessary or desirable, the base of the holder hasassociated therewith a soft flexible rubber instead of the moldingcompound. 7

While it is believed that from the foregoing description the nature andadvantages of the invention will be readily apparent, I desire to haveit known that I do not limit myself to what is herein illustrated anddescribed and that such changes may be re- 2 sorted to when desired asfall within the scope of ,what is claimed.

What I- claim is A dental X-ray film holder comprising a base adapted tobe arranged between the teeth of the patient, said base having anopening therethrough, and oppositely beveled walls above and below saidopening, a modeling composition of relatively soft material adapted tobe received by said opening, and adapted to receive the impression ofthe teeth when hit upon to. maintain the holder in the mouth of thepatient, and means forming part of said holder for supporting a filmfixed relatively thereon.
